Properties of Shape - Compare Angles - Starter

In a mathematics session for Year 4 students during the Summer Term, the class embarks on a series of tasks designed to sharpen their arithmetic skills and understanding of geometric properties. The 'Fluent in Four' revision segment prompts students to solve multiplication problems, such as finding a number that, when multiplied by 7, equals 42, and discovering what number multiplied by 7 gives a product of 426. Additionally, students tackle time-telling exercises, such as identifying the time as 17 minutes past 5, and explore angles by determining the number of right angles in fractions of a turn.

The lesson also includes a critical thinking challenge where students must decide whether two shapes have the same perimeter, as suggested by a character named Leanna. Pupils are encouraged to form their own opinions and provide explanations for their answers. For instance, they might observe that one shape has a perimeter of 16 squares while the other has 14, noting that although the area is the same, the perimeters differ. Finally, the children practice their subtraction skills by solving number sentences to find the difference, such as subtracting fractions to determine that six-sixths minus three-sixths equals one-half.
